Building an Induction Heater for Steel & Aluminium

[D44]

Hi guys

I'm looking to make an induction heater to heat bits of steel and aluminium (maybe 15mm by 25mm).

Can anyone recommend a good source of information in terms of calculating the various parameters and other general information? I've looked at many websites but a lot of them seem to be heating things much smaller than what I'm looking to heat and I don't want to copy someone's idea. I'd like to do it myself.

Cheers

About 25yrs ago a friend of mine was working on his MS with the http://www.netl.doe.gov/about/arc_history.html on a this very problem. Maybe that would be another place to look.
